| abstract | A master oscillator, vertical emission (MOVE) laser (300) includes an oscillatorn(301), a coupling region (306), and vertical-cavity amplifier region (304) formed on ancommon substrate (305). The coupling region (306) may include separately definednexpansion (302) and grating (303) regions. Single-mode radiation of the oscillator (301)npasses through the expansion region (302), which is a passive region that provides spatialnexpansion of the propagating single-mode radiation wavefront with little or no gain. Thenexpanded single-mode radiation from the expansion region passes through the gratingnregion (303), which provides coupling of the relatively broad wavefront from thenexpansion region into the cavity of the vertical-cavity amplifier. The expansion andngrating regions may be configured to reduce or eliminate reflection of single-modenradiation propagating within the vertical-cavity amplifier back toward the oscillator. Thencavity of the vertical-cavity amplifier (304) is relatively broad when compared to thencavity of the oscillator. The vertical-cavity amplifier operates as a low-gain-per-passnamplifier for incident single- mode radiation generated by the oscillator. Thus, radiationnof relatively low optical power emitted from the oscillator controls single-mode radiationnof relatively high optical power emitted by the vertical-cavity amplifier. |
